CTEK CS One battery charger

The new CS One from CTEK is a simple, buttonless unit that offers hassle-free charging technology. Its APTO (adaptive charging) system does all the thinking for you – there’s no need to worry about battery type, size or even positive and negative clamps, so it’s extremely safe and easy to use. The spark and polarity free clamps will automatically recognise positive and negative terminals so you’ll never make a wrong connection again. It automatically delivers charging and conditioning programmes for any 12V lead-acid or lithium battery, without the need to select modes or press any buttons. Plus, a countdown display shows how long it’ll be until you can use the battery, while a temperature sensor can alter the charging rate to suit cold or hot conditions.
